Here are two preparatory steps to take if you'll be using a cleaner's high-pressure cleaning service.

Ensure the surfaces you're getting washed are in good condition

Before booking this service, you should ensure the surfaces you're getting washed are in good condition. For example, if you're having your patio's paving stones washed, you should check that each paving stone is stable and that none of its corners or other edges are crumbling. You should also check that there are no gaps in the mortar that binds these paving stones together. Similarly, if you'll be having the cleaner wash an exterior wall that's covered in render, you should ensure that the render is not peeling.

The reason for this is if there are any of the above-mentioned issues with the surface and you instruct the cleaner to pressure wash it anyway, that surface will probably get more damaged. In the case of a damaged patio, the existing cracks or crumbling edges could worsen and the mortar could loosen even further. Likewise, if you tell the cleaner to point their pressure washer at a wall with the damaged render, more of the render will get pushed off the wall by the equipment. Additionally, instructing the cleaner to wash this type of damaged surface could also endanger them as, for example, pieces of the broken paving stones could ricochet off the patio and hit the cleaner.

In contrast, if you fix any issues with the surfaces that need to be washed beforehand, the cleaner will have no difficulty washing them without causing damage and they won't have to risk injuring themselves by doing this task.

Remove obstacles to maximise the results of the pressure washing

You may also need to spend time removing obstacles from the area that's to be cleaned to maximise the results of the pressure washing. For example, if you're having an old patio washed and there is lots of moss and weeds growing between the stones, removing this plant matter will ensure the cleaner can use their equipment to push every bit of dust and dirt out from underneath it (whilst the pressure washer might be able to push off some moss, it probably won't remove all of it and won't be able to pull out any deeply-rooted weeds).

Likewise, if you have an awning attached to the wall you want pressure washed, you should not just roll this up but, if possible, remove both the awning and the wall brackets; this will allow the cleaner to access the whole wall and will also mean that they won't have to spend any of the time you have booked them for trying to manoeuvre their equipment around the rolled-up awning or brackets to avoid striking them with the water jet.

If you need high-pressure cleaning, reach out to a cleaning company in your area.
